Melania Trump‘s spokeswoman says the first lady “wasn’t aware” that her verified personal Twitter account had “liked” a tweet that mocked her marriage to President Donald Trump.

On Tuesday evening, the former model’s Twitter account “favorited” writer Andy Ostroy’s tweet and viral GIF of her dramatic change in facial expressions at the inauguration, when she smiled, then scowled, after the president glanced in her direction. In his anti-Trump tweet, Ostroy joked: “Seems the only #Wall @realDonaldTrump‘s built is the one between him and @FLOTUS #Melania #trump.”

“The First Lady wasn’t aware of any of this until I brought it to her attention,” Melania’s communications director, Stephanie Grisham, tells PEOPLE, adding: “It isn’t her primary account and we have since changed the passwords.”

The tweet was subsequently un-“liked” by the first lady’s account later on Tuesday night.

The @MELANIATRUMP account, which has been registered since January 2010, is separate from the official @FLOTUS account that the first lady and her staff have been using since the president was sworn in.

The only other tweet she has favorited was from 2012 when she said, “Hello Twitter!”

Though it appears the first lady’s account may have been hacked, Twitter had an absolute field day over the “like” nonetheless.

After Ostroy received a notification that Melania’s account had liked the tweet, he tweeted: “I suspect this isn’t a real account for @flotus,” though it was quickly proved that the account was verified.
